Basic format (Author-Date Style)
In addition to having a references list at the end of your
paper, you must give credit to sources that you use within your paper. Usually
the author's last name and publication date are enough for the reader to
identify the complete reference in the references list. See the examples below
for variations of this general rule.
Author's name in text
If you cite the author's name in your paper, cite only the
publication year in parentheses after the author's name.
Example
In Silent Spring, Carsen (1962) made an intelligent and
passionate case for the immediate cessation of careless and pervasive pesticide
use.
References
Carsen, R. (1962). Silent spring. Greenwich, CT: Fawcett.
APA Manual 3.94 (p. 207)

Author's name in reference
If you do not cite the author's name in your paper, then
include both the author's last name and the publication year in parentheses at
the end of the sentence separated by a comma.
Example
Silent Spring was one of the first books to discuss
dangers of pesticide use (Carsen, 1962).
References
Carsen, R. (1962). Silent spring. Greenwich, CT:
Fawcett.

No author listed (cite by title)
When there is no author listed for a work, include the first
few words of the title followed by the publication year in parentheses at the
end of the sentence.
Example
Many in the liquor industry argue that the ban on television
liquor advertising gives those in the beer and wine industry an unfair advantage
("Liquor Advertising," 2002).

Citing part of a work (page and paragraph numbers)
Page numbers
When you quote or paraphrase a specific part of a print or
online source give the relevant page, chapter, figure, table or equation in
parentheses at the end of the sentence after the author's last name and
publication date.
Example
"Time management is an important survival skill" (Brown, 2003,
p. 6).

Onefile database.
Paragraph numbers
In an online source that does not provide page numbers, give
the paragraph number, preceded by the ? symbol or the abbreviation para. after
the author's last name and publication date.
Examples

years (Assel, 2004, para. 5).

Section headings
If there are no page or paragraph numbers, cite the section
heading and number of the paragraph following it to direct the reader to the
information.
Example
According to Jones (1994), binge drinking is widespread on
college campuses (Conclusion section, para. 1).

the publication date the first time you refer to a work and in each new
paragraph. If you cite the work again in the same paragraph, do not include the
year of publication.
